[The effect of euthyscope- and occlusion therapy in cases of convergent strabismus. Comparative, prospective examinations (author's transl)].

1. 63 children with strabismus and amblyopia (average age 7 years) were chosen at random to be treated either with occlusion or with the Euthyscope followed by occlusion. No significant difference was apparent after comparison of both forms of treatment. 2. Six more children were occluded for several months without success and were then treated for two months with the Euthyscope followed by further occlusion. In four of these cases pleoptic treatment proved to be temporarily successful. 3. In addition, 14 children with microstrabismus and amblyopia, and 17 children with amblyopia ex anisometropia showed a distinct improvement of the visual aciuty after occlusion. An 18-year-old patient with microstrabismic amblyopia achieved normal visual acuity. 4. Euthyscope treatment was used in amblyopic patients who had lost their good eye. In the case of an 18-year-old patient the distant visual acuity increased to 0.6. The increase in the near vision and the speed of reading continued to improve for several years. 5. Papilla-Macula-Relationship: 47 amblyopes were compared with 8 anisometropic and 16 microstrabismic patients as well as with 32 normal subjects. In these groups no significant difference in the papilla-maculadistance was apparent. 6. Refraction: In amblyopic eyes there were no significant refractive errors between fixing and non-fixing eyes. Conversely, in patients with microstrabismus and those with anisometropic a significant difference was found.
